Wake shaping system for a boat

ABSTRACT

A boat comprising a wake shaping system comprising starboard and port wake shaping devices located aft of the transom. Each wake shaping device is operable to move between a first, non-deployed position behind the transom and a second, deployed position extending outside the side of the hull or below the transom. When the starboard wake shaping device is in the deployed position, a port wakesurf wake is created. When the port of the wake shaping device is in the deployed position, a starboard wakesurf wake is created. When neither wake shaping device is deployed, a symmetrical wakeboard wake is created.

TECHNICAL FIELD

The present disclosure generally relates to a wake shaping system for a boat, and more particularly, to a wake shaping system for wakesurfing behind an inboard boat.

BACKGROUND

During the first half of the twentieth century, waterskiing emerged as a popular recreational activity, allowing individuals to ski behind a boat on a lake, river, or ocean. The first waterski boats, however, were wooden boats that produced large wakes because of the weight of the boats. In search of a smaller wake, which is advantageous for waterskiing, the first fiberglass inboard waterski boat was designed and built in the early 1960s. Throughout the 1970s, 1980s, 1990s, and today, inboard ski boat manufacturers continue to refine ski boat designs to produce the smallest, softest, cleanest wakes behind the boat at speeds in excess of 25 mph. These competition waterski boats, which are still manufactured today, are closed bow, flat-bottomed boats with a direct drive inboard engine mounted in the center of the boat. The shape of the hull is optimized to create small, soft wakes for tournament waterskiing, but the hull does not perform well on public waterways, which are often larger and more crowded than private waterski lakes. In addition, because the ski rope is attached to a ski pylon in front of the engine, passengers cannot sit in the back of the boat while a skier is skiing because the ski rope swings back and forth at head-height above the rear seat. As such, a day on the lake for a competition water-skier may only include one or two other people.

In the 1990s, inboard boat manufacturers began designing and manufacturing larger boats as a result of increased demand for boats that were comfortable for an entire family and that performed better on larger, public waterways. At the same time, and a result of the growing popularity of snowboarding, wakeboarding emerged as a popular alternative to competition slalom waterskiing. Unlike waterskiing, where a waterskier attempts to stay low on the surface of the water in order to increase his or her speed back and forth around buoys set in a slalom course, a wakeboarder attempts to perform tricks such as flips (“inverts”) or spins when jumping the wakes behind the boat. Therefore, a new style of inboard boat emerged that provided wakeboarders with larger, firmer wakes needed to perform wakeboard tricks.

Compared to competition waterski boats, wakeboard boats are larger, open bow boats with a deep-V hull, a V-drive engine mounted in the rear of the boat, and a tower to attach the tow rope at an elevated point above the boat. By placing the engine in the rear of the boat and connecting the rope to the tower above the boat, wakeboard boats allow passengers to sit in wraparound-style seating while a wakeboarder is towed behind the boat. Wakeboard boats also include ballast systems to weight the hull of the boat down and displace more water, and therefore generate larger wakes behind the boat for wakeboarding. These ballast systems may be in the form of removable ballast bags, factory-installed ballast bags, internal hard plastic tanks, or lead weight positioned throughout the boat. With each ballast system, the goal is to create large, firm, and symmetrical wakes approximately 50 to 80 feet behind the boat when the boat is travelling between 18 and 25 mph.

In recent years, wakesurfing has emerged as a popular counterpart to wakeboarding, allowing a surfer to surf behind the same wakeboard boat without having to travel to the ocean. Compared to wakeboarding, wakesurfing is easier to learn, has a lower risk of injury, is performed closer to the boat, and has become just as popular, if not more popular, than wakeboarding. Wakesurfing, however, requires a different ballast configuration in a traditional wakeboarding boat than wakeboarding. The desired wakesurfing wake is located on one side (starboard, right, or driver's side; port, left, or passenger's side) of the boat, creating an asymmetrical wakesurf wake between approximately 5 and 20 feet behind the boat when the boat is travelling between 5 and 15 mph.

Conventional wakeboard boat ballast systems place hundreds or even thousands of pounds of water ballast in bags or tanks in the bow, midship, port stern, and/or starboard stern sections of the boat. For wakeboarding, all ballast is typically filled, creating a large, firm, symmetrical wake behind the boat at wakeboarding speeds. For wakesurfing, the ballast is only filled on one side of the boat, leaving the ballast on the opposite side empty. This configuration “sinks” or “lists” one side of the boat, tipping the boat and creating a large, unsymmetrical wake for wakesurfing on the listed side of the boat at wakesurfing speeds.

Conventional wakesurfing ballast configurations, however, have many disadvantages. First, by weighting only one side of the boat, the boat is unbalanced and difficult to control at slower speeds. After a surfer falls, it is difficult and dangerous to return to the fallen surfer at slower speeds and with reduced visibility. Second, traditional ballast takes up a large portion of the boat's storage capacity. Third, moving the ballast from one side to the other to create a surf wake on the opposite side can be difficult, time consuming, and cumbersome. With removable ballast tanks, an external pump is needed to fill or empty the tanks with water. These external pumps often leak and require priming in order to siphon water out of the tanks when emptying. Emptying one side and filling the opposite side with just one pump may take 20 minutes or more, depending on the speed of the pump. With internal hard ballast tanks, the ballast tanks may be filled or emptied with internal ballast pumps at the same time, reducing the time to switch sides, but still may take 10 minutes or more, depending on the speed of the pumps. As a result, in order to minimize the time spent filling and emptying ballast during a day on the lake, all wakeboarding is typically done at the same time, all left-side (port) surfing is done together, and all right-side (starboard) surfing is done together. However, this is inconvenient and requires undesired advanced planning to set the ballast for each rider's desired ballast configuration.

As a result, an improved wake shaping system that can be used interchangeably for wakeboarding, left-side surfing, and right-side surfing with one ballast configuration and without requiring filling or emptying of individual ballast tanks, listing the boat dangerously to one side, or lifting of the transom, which reduces the size of the wakeboarding or wakesurfing wakes is desired.

BRIEF SUMMARY

Disclosed herein is a wake shaping system for wakeboarding and wakesurfing behind a boat, and preferable for wakesurfing behind an inboard wakeboard boat.

In an embodiment, a boat comprising a wake shaping system for wakeboarding and wakesurfing is disclosed, the boat comprising a hull comprising a bow and a transom, starboard and port sides, a longitudinal axis extending from the bow to the transom along a centerline, a lateral axis extending from the port side to the starboard side substantially perpendicular to the longitudinal axis, and a transom axis extending from an upper edge of the transom to a lower edge of the transom substantially perpendicular to the longitudinal axis. The wake shaping system may comprise starboard and port wake shaping devices located aft of the transom. Each wake shaping device is operable to move between a first, non-deployed position and a second, deployed position. In the first, non-deployed positions, each wake shaping device does not extend outside or below the transom. In the second, deployed positions, a portion of each wake shaping device extends outside or below the transom.

When the starboard wake shaping device is in the deployed position, a port wakesurf wake is created. When the port wake shaping device is in the deployed position, a starboard wakesurf wake is created. When the second portions of the starboard and port wake shaping devices are both in the non-deployed positions, a symmetrical wakeboard wake is created.

In an embodiment, each wake shaping device may comprise a first mounting portion coupled to the transom of the boat and a second plate portion pivotably coupled to the first mounting portion

In an embodiment, the first mounting portions of the first and second wake shaping devices are mounted directly to the transom at the starboard and port first mounting portions, and the first mounting portions of the first and second wake shaping devices are mounted directly to the transom slightly away from the starboard and port sides of the hull and above the lower edge of the transom.

In an embodiment, the second plate portion of the starboard wake shaping device pivots relative to the first mounting portion of the starboard wake shaping plate along a starboard pivot axis, wherein the starboard pivot axis is angled along the transom from the centerline to the starboard side approximately 40° above the lateral axis.

In an embodiment, the second plate portion of the port wake shaping device pivots relative to the first mounting portion of the port wake shaping plate along a port pivot axis, wherein the port pivot axis is angled along the transom from the centerline to the port side approximately 40° above the lateral axis.

In operation, when the second plate portion of the starboard wake shaping device is in the second, deployed position, the second plate portion extends between approximately 2″ and 3″ beyond the starboard side of the hull and extends between approximately 2″ and 3″ beyond the lower edge of the transom. When the second plate portion of the port wake shaping device is in the second, deployed position, the second portion extends between approximately 2″ and 3″ beyond the port side of the hull and extends between approximately 2″ and 3″ beyond the lower edge of the transom.

In an embodiment, the starboard and port worm drives are operable to pivot the second plate portions of the starboard and port wake shaping devices between the first, non-deployed positions and the second, deployed positions. The starboard and port worm drives are controlled by an electronic device or by mechanical means.

The first and second portions of the starboard and port wake shaping plates may be constructed from stainless steel or from fiberglass.

As disclosed herein, the starboard and port wake shaping devices do not provide lift to the transom and do not list the hull in either the first, non-deployed positions or the second, deployed positions.

DETAILED DESCRIPTION

While the making and using of various embodiments of the present disclosure are discussed in detail below, it should be appreciated that the present disclosure provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the disclosure and do not limit the scope of the disclosure.

To facilitate the understanding of this disclosure, a number of marine terms are defined below. Terms defined herein have meanings as commonly understood by a person of ordinary skill in the areas relevant to the present disclosure. “Starboard” refers to the right-hand, or driver's, side of the boat. “Port” refers to the left-hand, or passenger's, side of the boat. “Bow” refers to the front of the boat. “Transom” and “stern” refer to the rear of the boat. Terms such as “a”, “an”, and “the” are not intended to refer to only a singular entity, but include the general class of which a specific example may be used for illustration. The terminology herein is used to describe specific embodiments of the disclosure, but their usage does not limit the disclosure, except as outlined in the claims.

Various embodiments of a wake shaping device for a boat are described. It is to be understood, however, that the following explanation is merely exemplary in describing the devices and methods of the present disclosure. Accordingly, several modifications, changes, and substitutions are contemplated.

As a boat travels through water, the hull of the boat displaces water both downwardly from the bottom of the boat and outwardly from the sides of boat, creating a cavity behind the transom of the boat. The displaced water then re-converges behind the boat, filling the cavity behind the transom, and creating a wave at a point of convergence. The wave extends from the point of convergence in a V-shape, creating wakes behind the boat that are suitable for wakeboarding or wakesurfing. Because of known principles of fluid dynamics, the port side of the boat displaces water that creates the starboard wake past the point of convergence and the starboard side of the boat displaces water that creates the port wake past the point of convergence.

Wakeboard boat hulls are specifically designed with a running surface that shapes wakes to make optimum wakeboarding wakes that are large, firm, and symmetrical on both sides behind the boat at wakeboarding speeds and rope lengths, i.e., approximately 50 to 80 feet behind the boat when the boat is travelling between 18 and 25 mph. Therefore, wakeboard boat manufacturers do not want to change the running surface of the hull at wakeboard speeds in order to maintain optimum wakeboard wakes for wakeboarders.

In order to surf behind a wakeboard boat, however, the convergence point should delayed on one side, creating a large, curling, and asymmetrical wake behind the boat at wakesurfing speeds and rope lengths, i.e., approximately 5 and 20 feet behind the boat when the boat is travelling between 5 and 15 mph. In order to delay the convergence point on one side, the running surface of the boat should be manipulated. In order to create a left-side, or port, wakesurf wake, a starboard wake shaping device may be used to manipulate the starboard running surface, delaying the convergence point on the starboard side and shifting it starboard, therefore creating a smoother port wakesurf wake beyond the convergence point that is optimized for left-side wakesurfing. Conversely, in order to create a right-side, or starboard, wakesurf wake, a port wake shaping device may be used to manipulate the port running surface, delaying the convergence point on the port side and shifting it port, therefore creating a smoother starboard wakesurf wake beyond the convergence point that is optimized for right-side wakesurfing.

Professional athletes, recreational purists, and families often want to wakeboard and wakesurf on the same days behind the same boat and in back-to-back sets, any wake shaping device mounted to the transom of the boat should remain fully within the cavity behind the transom of the boat at wakeboard speeds, and therefore not change the running surface of the hull while wakeboarding, but should manipulate the running surfaces of one side of the boat at wakesurf speeds, and therefore create asymmetrical wakesurf wakes.

In operation, if a user selects a “Surf Left” button 306 on the electronic device 300, for example, the electronic device 300 may activate the starboard wake shaping device according to factory or user presets. When activated, the starboard worm drive may pivot the starboard wake shaping device approximately 90° from the first, non-deployed position to the second, deployed position. With a “Surf Left” selection, the port wake shaping device would remain in the non-deployed position behind the transom of the boat and the optional center cavitation plate may be used, as necessary, to help get the boat on plane. In an embodiment, the electronic device 300 presets for surfing a left-side, or port, wakesurfing wake may be 0% port wake shaping device, 0% center cavitation plate, and 100% starboard wake shaping device.

If a user selects a “Surf Right” button 308 on the electronic device 300, the electronic device 300 may activate the port wake shaping device according to factory or user presets. When activated, the port worm drive may pivot the port wake shaping device approximately 90° from the first, non-deployed position to the second, deployed position. With a “Surf Right” selection, the starboard wake shaping device would remain in the non-deployed position behind the transom of the boat and the optional center cavitation plate may be used, as necessary, to help get the boat on plane. In an embodiment, the electronic device 300 presets for surfing a right-side, or starboard, wakesurfing wake may be 100% port wake shaping device, 0% center cavitation plate, and 0% starboard wake shaping.

Although not shown, if a user selects “Wakeboard,” both the starboard and port wake shaping devices may remain in the non-deployed positions behind the transom of the boat and the optional center cavitation plate may be used, as necessary, to help get the boat on plane. In an embodiment, the electronic device 300 presets for wakeboarding may be 0% port wake shaping device, 0% center cavitation plate, and 0% starboard wake shaping device.

As depicted in FIG. 13, the user may also have the option of controlling the port wake shaping device, the starboard wake shaping device, and the center cavitation plate manually in order to customize the wakeboarding and/or wakesurfing wakes behind the boat.

As depicted in FIG. 14, the second view of the electronic device 300 may display the current speed of the boat, a desired speed of the boat, and the current wake settings, i.e., Surf Left, Surf Right, or Wakeboard.

FIG. 15 illustrates a profile view of mechanical means 500 for controlling the wake shaping system of FIG. 1, in accordance with one embodiment of the present disclosure. The mechanical means 500 may be located at the driver's helm proximate to a throttle lever and may be used in combination with the electronic device 300 controls discussed in relation to FIGS. 13 and 14. The mechanical means 500 may comprise a surf side switch button 502, a port wake shaping device toggle switch 504, a starboard wake shaping device toggle switch 506, and a center cavitation plate toggle switch 508. The mechanical means 500 may be used to switch between a left-side wakesurf wake, a right-side wakesurf wake, or a wakeboard wake.

If a user wants to surf a left-side, or port, wakesurf wake, for example, the starboard wake shaping device toggle switch 506 may activate the starboard worm drive and may pivot the starboard wake shaping device approximately 90° from the first, non-deployed position to the second, deployed position. In an embodiment, the electronic device may display the settings for surfing a left-side, or port, wakesurfing wake and may be 0% port wake shaping device, 0% center cavitation plate, and 100% starboard wake shaping device.

If a user wants to surf a right-side, or starboard, wakesurf wake, the port wake shaping device toggle switch 504 may activate the port worm drive and may pivot the port wake shaping device from the first, non-deployed position to the second, deployed position. In an embodiment, the electronic device may display the settings for surfing a right-side, or starboard, wakesurfing wake and may be 100% port wake shaping device, 0% center cavitation plate, and 0% starboard wake shaping device.

Center cavitation plate toggle switch 508 may be used to control an optional center cavitation plate to help get the boat on plane and/or control the trim angle of the bow of the boat relative to the stern of the boat.

The surf side switch button 502 may be used to switch the side of the wakesurf wake while the boat is travelling and a surfer is surfing behind the boat with the single touch of a button. For example, if a surfer is surfing on a left-side, or port, wakesurf wake and wants to switch to a right-side, or starboard, wakesurf wake, the driver of the boat may depress the switch button 502. Via controls from the electronic device 300 (not shown), the wake shaping system 200 may switch instantaneously from 0% port wake shaping device, 0% center cavitation plate, and 100% starboard wake shaping device to 100% port wake shaping device, 0% center cavitation plate, and 0% starboard wake shaping device.

Conversely, if a surfer is surfing on a right-side, or starboard, wakesurf wake and wants to switch to a left-side, or port, wakesurf wake, the driver of the boat may depress the switch button 502. Via controls from the electronic device 300 (not shown), the wake shaping system 200 may switch instantaneously from 100% port wake shaping device, 0% center cavitation plate, and 0% starboard wake shaping device to 0% port wake shaping device, 0% center cavitation plate, and 100% starboard wake shaping device.

Depressing the switch button 502 may further activate a horn, light, or other signaling mechanism that provides a signal to a surfer behind the boat that the wakesurf wakes are shifting and it is the preferred time to attempt to transfer from a left-side surf wake to a right-side surf wake or vice-versa.

While not depicted in FIGS. 13-15, the electronic device 300 and/or mechanical means 400 may also be used for controlling an internal ballast system in the boat. In an embodiment, the electronic device 300 or mechanical means 400 may be operable to control one or more ballast gates located at the stern of the boat. When the boat is sitting in the water and not moving and the ballast gates are opened, one or more internal ballast tanks may be filled using gravity until the tanks are full. After the tanks are full, the one or more gates may be closed, ensuring that the ballast tanks remain full when the boat is running and is on plane. When the boat is running and is on plane, the bow of the boat may be higher than the stern. If the one or more ballast gates are opening while the boat is on plane, the one or more internal ballast tanks may be emptied using gravity until the tanks are empty. After the tanks are emptied and before the boat is stopped again, the one or more gates may be closed, ensuring that the ballast tanks remain empty when the boat is stopped and sitting in the water. In an embodiment, the electronic device 300 or mechanical means 400 may also be operable to control an internal ballast system comprising a plurality of hard tanks or bags filled and emptied by ballast pumps.

In an embodiment, the electronic device 300 may further be operable to control the speed of the boat, control the sound system, and display water and/or air temperatures, among various other features.

As disclosed herein, the wake shaping system 200 can be used interchangeably for wakeboarding, left-side surfing, and right-side surfing with one ballast configuration and without requiring filling or emptying of individual ballast tanks To create advance, large wakeboard and wakesurf wakes, a full ballast configuration is used in conjunction with the wake shaping system 200 disclosed herein. To create intermediate, smaller wakeboard and wakesurf wakes, less than full ballast may be used in conjunction with the wake shaping system 200 disclosed herein. In addition, the wake shaping system 200 does not require dangerous listing of the boat to one side in order to create surfable wakesurf wakes. The wake shaping system 200 also does not lift the transom of the boat, which may undesirably reduce the size of the wakeboarding or wakesurfing wakes.
